'92 3.3L Olds Cutlass Ciera, intermittent code 42, bad stumbling
1993 Grand Am 3.3L V6 (6-204) - Solved intermittent "Code 42 - electronic spark timing" issue by replacing Mass Air Flow sensor, after checking all wires in harness (and replacing some) between the ECM and ICM, checking all connections, and replacing all the other sensors. All work prior to replacing MAF improved performance but did NOT solve intermittent Code 42 problem.. Never got a "MAF sensor" Code 34.

Was the MAF sensor tracking with throttle and were there any dropouts? Does the MAF sensor by any chance share a reference ground in a cable with something else? If something bad in the MAF sensor electronics was polluting the ground, you could have seen spreading problems like that. I have to say that's a hell of a weird one. I'm very curious what the failure mechanism was. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
